In Photoshop, you can easily divide the image into zones using point and click and it automatically generates the corresponding HTML with image slices addressed in tables. Gimp also has a Slice (Filter > Web > Slice) but it is so rudimentary and, as far as I can see, does not allow point and click selection of slices.
I am wondering if the functionality can be added into Gimp, or there are other Linux software to do this. I hate to return to Windows just to do this simple task which I happen to use frequently. Thanks in advance for your suggestions.
